FIELD INVESTIGATION ON SEDIMENT TRANSPORT INTO THE SUBMARINE CANYON IN THE FUJI COAST WITH THE NEW TYPE TRACERS

Abstract

The Fuji coast in Japan is one of the beach which is suffering from coastal erosion. One reason for erosion is seemed to be the offshore sediment transport through the submarine canyon in front of eroded area. The present paper concerns the field investigation in order to confirm the sediment transport into the submarine canyon with two new type tracers. One tracer is the artificial sand and gravel made of the hard plastic. The other is the tracer with an ultrasonic transmitter. These tracers are very effective for tracking the sediment.
